This session will focus on the application and structure of ASME B18.24 2023, emphasizing how specification and standard references are constructed and applied within the fastener industry. Participants will learn to break down a spec/standard part number to identify key characteristics and dimensional attributes, as well as how to build a complete spec based part number using vendor provided data. The discussion will also cover the operational advantages of standardized references—including reduced procurement time, lower cost variability, and fewer configuration errors—and explain how consistent use of specifications and standards supports long term product sustainability, interoperability, and lifecycle support for critical systems such as weapons platforms and other defense related equipment.
